SOLDERING IRON.

Application filed .Tune 18, 1925. Serial No. 38,007.

This invention relates to improvements in soldering or branding irons, and has for its principal object to provide one which employs gasoline as a heating medium for the iron. A

Une of the important obj ec-ts of the present invention is to provide a gasoline heater soldering iron wherein the torch is embodied in the handle for the iron, thereby rendering the device easy to be handled when in use.

A still further object is to provide a soldering iron of the above mentioned character, which is simple in construction, inexpensive, strong and durable, and further well adapted for the purpose for which it is designed.

Other objects and advantages of the invention will become apparent during the course of the following detailed description.

In the accompanying drawing, forming a part of this application, and in which like reference characters designate like parts throughout the same:

Figure 1 is a view partly in side elevation, and partly in section of the soldering iron, embodying my invention, and

Figure 2 is a transverse section taken approximately on the line 2 2 of Figure 1.

In the drawing, wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the frame of my improved soldering iron, the iron 2 having its rear end supported in the forward end ofthe frame, in a detachable manner, by means of the clamp 3. An elongated cylindrical gasoline chamber 4 has its forward end supported in the rear end of the frame 1, by means of the clamp 5, saidgasoline chamber extending rearwardly of the frame, in the same plane therewith.

The forward end of the gasoline chamber 4, has associated therewith the removable closure 6, and carried by the closure is the burner head 7, the -saine being pro-vided with a rotary valve 8, whereby the flow of gas from the chamber 4 to the burner head p may be regulated. The burner 7 is disposed in spaced relation with respect to the rear end of the iron 2, as is clearly illustrated in Figure 1.

An air pump designated generally by the numeral 9 is associated with the gasoline chamber 4 and the same com rises the cyl nder 1Q, which extends .ongitudinally within the gasoline chamber, the same being supported at its rear end in the rear end of the chamber. A curved pipe 11 has its shorter arm conununicating with the forward end of the cylinder 10, through the medium of the fitting 12. The longer arm of the pipe lever extends rearwardly within the gas chamber 4, as is illustrated in Figure 1. Operable within the cylinder 10 is the'piston 13, the piston rod 14 thereof eX- tending through the cylinder and through the closure 15 provided at the rear end of the cylinder, a suitable handle 16 being carried by the rear end of the piston rod or plunger for facilitating the actuation thereof. Gasoline is admitted into the chamber 4 through a suitable inlet opening 17 provided therefor in the side of the chamber, a suitable closure cap 18 being provided for normally maintaining the opening in a closed position.'

A handle 19, formed preferably of wood encircles the gasoline chamber 4, substantially the entire length thereof.

The inclusion of the air pump in connection with the gasoline chamber, enables the gasoline to become co-mingled with the air and therefore forms a gas which passes into the burner head when the valve 8 is opened. The gas is ignited at theburner head and the flame will be directed against the rear end of the iron thus enabling the latter to be heated very easily and quickly.

A soldering iron or branding iron of the above mentioned character Vwill at all times noY be ready for use, the same being heated sorted to, without departing from the spirit of the invention 0r the scope of the apended claim.

lVIiat I claim is: Y

A soldering iron comprising in combination, aframe including a pair of opposed bars, an iron extending forwardly from the forward end of the fra-me, a band encircling the Vforward end of the bars and the rear portion of the iron for detachably securin the latter between the forward ends of the` are,

a Cylindrical fuel 'ohambe supported at is 'forward end in the rear end of the aine, an additional bend encircling the real p01'- tions of the opposed bars and the adjacent portion of the chamber foi detacliably securing the latter between the rear ende of the bars, a burner extending from the fol'- Waid end o' the fuel chamber and teiininafng in spaced relation with respect to lhe rear end of the iron, a cut off' valve associated with *bheV buiner, and an air pump within the fuel chamber.

In testimony whereof I aiix my signature.

PETER BLDSEN.
